Really?
Hmmm, reboot your computer and scan again and post here on SF if the virus is still there.

I did what you said and it is still there. When I go to My Computer, I do not see a folder called "D:\System Volume Information"
Is there a way to get to that folder so I can delete the virus file manually?

Have you gone to tools -> Folder Options -> View -> Hidden Files and Folders -> Show hidden files and folders, and deleted it manually.

AVG should inform you on the name of the exe that is the virus, delete it manually, if it cannot be deleted, CTRL ALT DEL, go to processes tab, and end the process that is the virus (If there is an instance of it)

The procedure that was given in that website I noted above fixed the problem, so it's too late to do what you suggested.
